Specification of Letters Patent.

Patented Jan. 25, 1916.

Application filed September 26, 1914. Serial No. 863,734.

To all whom it may concern Be it known that I, FRANK MCCORMICK, a citizen of the United States, res ding at Monroe. in the county of Snohomish and State of Washington, have invented certain new and useful Impro ements in Stump- Extractors. of which the following is a specificat on, reference being had to the accompanying drawings.

This invention relates to certain improvements in stump extractors; and the o -ject of the invention is to provide a novel and improved device of this general character of a portable natu e so as to be easily mo'ed from point to point, and comprising novel and improved means for the development of great power with a minimum of exe t on.

The in ent on consists in the details of constrrction and in the combination and arrangement of the se eral parts of mv impro ed stump extractor whereby certain important advantages are attained and the de ice is rendered simpler. less expensive and otherwise more convenient and advantageous for use. all as will be hereinafter mo e fully set forth.

The no el features of the invent on will be carefully defined in the appended claim.

In order that my invention may be the better undersrood, I will now proceed to describe the same with reference to the accom anving drawings, wherein Figure 1 is a view in top plan of a stump pu ling de ice constructed in accordance w th an em od ment of my in ent on: Fig. 2 is a sectional view taken substantially on the line 22 of Fig. 1: Fig. 3 is a front ele ational view of the device as he ein embodied: Fig. 4 is a sectional view taken substantially on the line 44 of Fig. 1; Fig. 5 is an enlarged fragmentary view in plan of a central port on of the sweep as herein embodied; and Fig. 6 is a detail View of a fulcrum pin herein embodied.

As di closed in the accompanving drawings. 1 denotes a bottom series of elongated parallel beams in predetermined transverse spaced relation and having superimposed therein a second series of elongated transverse loeams 2 and the adjacent extremities of said beams 1 and 2 are tied or connected by the transverse beams 3 interposed therebetween and in a manner which is believed to be clearly obvious.

The outer beams 1 are provided along their outer marginal portions with the depending runners 4 whereby the device may be readily transported from one 10- cality to the other as the requirements of practice may dictate. The beams 1 and 2 are provided with the elongated alined long tudinally spaced openings 5 through which the removable fulcrum pin 6 is adapted to be directed. the head of such pin being provided with a loop 7 whereby the same may be manipulated with convenience and facility. In order to reinforce or strengthen the beams 1 and 2 against the strain imposed upon the fulcrum pin 6, as will be hereinafter more fully set forth, I find it of ad antage to provide theopposed faces of the beams 1 and 2 with the longitudinally directed metallic straps 8 provided with the openings 9 adapted to register with the open ngs 5, hereinbefore referred to.

In order to brace the intermediate portions of the braces 1 and 2 against lateral strain. I find it of advantage to d spose through adjacent beams the inclined brace rods 9. In practice. I find it of advantage to have the brace rods 9 of adjacent beams disposed on such inclines as to intersect intermediate the beams and to have the various brac ng structures disposed in staggered relat on, as by this arrangement I have found that greater rigidity and strength results. Adapted to be disposed between the beams 1 and 2 is a sweep 10 of predeterm ned length and herein d sclosed as having its rear face provided with a reinforc ng strip 11 of metal and having the longitud nal central po tion of its rear face provided with spaced lugs 12 between which is adapted to be dis osed the anchoring pin 14 of the forwardlv directed clevis 15. The clevis 15 is adapted to have detachably engaged therewith and preferably through the medium of a hook member 16 an extrem tv of a flexible member 17 which is adapted to be disposed through an opening 18 produced in the forward transverse member 3 and be suitably secured to the stump or the like to be extracted. In order that the sweep 10 may be further reinforced against the strain or pressure imposed thereon during the extracting or pulling operation. I find it of ad antage to have embedded within the rear face of the sweep at its central portion a metallic block 19 serving in a manner which is believed to be clearly apparent. The forward face of the sweep 10 at opposite sides of its longitudinal center is provided with series of spaced lugs 20 which are adapted to receive there- 'between a fulcr-um pin 6.

I do not wish to be limited as to the character of power to be employed in connection with the sweep, although it will be readily understood that motor power may be employed with equal facility as draft animals.

In order that the device may be suitably anchored so as to permit the operation theeof, I secure to the opposite side faces of the rear extremities of the outer beams 1 the plates 21 having disposed therethrough the'pins 22 whereby the clevises 23 may be operatively engaged therewith. Any suitable means may be employed to coact with the clevises for anchoring the device to a stationary support, although I find in practice it is best to employ flexible members as ind cated in fragment at 24. 7

From the foregoing description, it is thought to be obvious that a stamp extractor constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is part cularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invent on is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

A device of the. character described comprising a base member, a removable fulcrum coacting with the base, a sweep, spaced lugs carried by the sweep adapted to receive the fulcrum therebetween, the face of the sweep opposite to the lugs being provided. with a reinforcing strip and having spaced lugs project ng therefrom. the portion of the sweep immediately adjacent the last named lugs having a metallic block embedded therein.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses.

FRANK MCCORMICK.
